Fans
Four internal hot-swap fan modules cool the switch unit. If an individual fan module
fails, the other fans continue to run, and the switch unit continues to operate
normally. You can replace a hot-swap fan module while the switch is operating.
Fan operation and internal temperatures are monitored. If the air temperature
exceeds a threshold, the environmental monitor displays warning messages.
Note: If a fan module fails, the maximum operating temperature drops from 40°C to
35°C (104°F to 95°F).
The Service ( ! ) LED flashes and the Fan LED flashes if there is a failure of one or
more fan modules. The failed fan module LED (rear panel) flashes to indicate a
failure.
AC power supply
The RackSwitch has two hot-swap redundant 150 W AC power supplies. Each
internal power supply has an individual IEC 320 power connector on the rear panel.
The power cord attaches to a universal grounded AC power source. You can
replace a hot-swap power supply module without powering off the switch or
disrupting switch functions.
